I got this two years ago for $67 and been pretty happy with it. Yes, it'll likely come apart at some point but being able to have an instant tent is incredibly convenient and gives me more time on the beach.

This is my favorite. The 2 person is about $80, and the 4 person is about $110. The biggest issue I've seen with pop ups is ventilation, and this one has ventilation in spades.
My parents got this 2-person Coleman pop-up for my son for Christmas. He loves it... not sure if the door placement would work for movie watching... but it’s a cinch to take up and down!
Get a pop-up tent, similar to this. I can't recommend that enough. Also, make sure you also have a shade tent, or at least something to provide decent shade, for the day.
I'm not a fan of the RTT because of the dog. You have to carry him up every night and if he has to pee you have to carry him down. If he jumps out from that high it's bad for the legs. Also there is a lot less room up there than you thing. For like $50 bucks you can get a pop up tent that goes up in seconds. It takes up much less room in the jeep or on the roof rack . I have a bunch of tent's for backpacking and car camping some as expensive as $350 but I settled on this https://www.youtube.com/watch?v=S9nSYkEq0aA one for car camping. It takes up some room but set up and take down is instant. it still takes lees room than a roof top and it doesn't make you top heavy. I think roof tops are on there way out unless they lower the prices significantly. Also if you ever have to go under a tree or parking garage they are a pain. $60 on amazon https://www.amazon.com/gp/product/B00FGPY9CE/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
Edit: I wanted to mention that I never use the tent stakes. unless its super windy the weight of my sleeping bag or packpack will keep it down.
Hi I'm looking for a space to camp! I will help split the tent camping cost. My tent is fairly small and I won't need much space. Looking to find a group so I don't have to shell out the full cost of camping. I play ukulele and am excited for firefly! Will be getting there thursday.
